Purvis and Wade had always wanted to explore Bond's past

The screenwriting duo who wrote or co-wrote 007's latest five outings spoke recently to Digital Spy about their desire to get Bond back to his roots.

The pair previously worked on the rebooting of 007's career, when they penned Daniel Craig's debut adventure, "Casino Royale", but there was more left to explore for these screenwriters.

"That idea [to go to Skyfall lodge] came very late in the day. It was in the last two weeks when we were working on the script," Wade said.

"The third act had been action stuff in a European city and we weren't very happy with it and we just felt it was ordinary. This idea came, and we wrote it up as a page and a half, ran it by Sam, Barbara and Michael and said we just want to tear up the third act and do a completely new thing.

"They said 'great'! They've always wanted to explore those areas."

Purvis added: "It's something you can only do once, so you've got to make sure you do it well."
